Figure 6.

Variation in the number of lateral gene transfer (LGT) events predicted depending on the transfer cost in phylogeny-based LGT prediction methods. The percentage of trees displaying at least one LGT event predicted for transfer costs varying between 3 (the default cost) and 30 is shown for three different methods: Notung, Ranger-DTL, and ecceTERA. Only the gene trees with the best reciprocal blast orthologs were used for Ranger-DTL and Notung. Trees with homologs only, or homologs and orthologs combined (blast E-value < 1 × 10⁻¹²), are shown separately for ecceTERA. The theoretical rare event threshold of 5% is indicated by a black dashed line.
